WIRE-CLOTH LATHING.

SPECIFICATION forming part of Letters Patent No. 394,602, dated December 18, 1888.

Application filed November 17, 1886. Serial No. 219,119. (No model.)

To all whom it may concern.-

' Be it known that I, WILLIAM ORR, a citizen of the United States, residing at Trenton, county of Mercer, and State of New Jersey, have invented certain new and useful Improvements in \Vire-Cloth Lathing, fully described and represented in the followin g specification and the accompanying drawings forming a part of the same. This invention relates to that general class of lathing material which is made of wire cloth or gauze.

The invention relates particularly, however, to a 'furring-strip, which is designed for use in connection with such lathing material, and to means for securing the wire-cloth to the t'urring-strip and the strip to the wall or ceiling. In using this class of lathing material for walls it is usually desirable to employ furring, in order not only to remove the lathing a sufficient distance from the wall to permit themortar to clinch, but also to provide an air-space between the plastering and the wall, while in the case of ceilings it is necessary to use furring-strips to properly support the lat-hing. As one of the principal objects in using this class of lathing material is to se cure a fire-proof structure, it is impracticable to employ wooden furring-strips in connection with it, and as a consequence iron strips of various forms have been employed for this purpose; but all of the forms which have heretofore been proposed have been open to objections more or less serious. In some cases the strips have been of such form as to not be sutliciently stiff without being too heavy. In other cases the forms have been such as to involve too great expense in their production; and in other cases they have been of such form that dit'ficulty was experienced in properly securing the wire-cloth to them. Another objection to the furring-strips heretofore proposed is due to the fact that they have aitorded no ready means for stretching the cloth, so as to prevent it from springing to too great an extent when the mortar was applied.

It is the object of the present invention to overcome, as far as may be, these difiiculties; and to that end the invention consists in a furring-strip, and in a m cans for attaching the strip to the wall or ceiling and the wire-cloth to the strip, which will now be described, reference being had to the accompanying drawings, in which-,-

Figure 1 is a view of a portion of the wall and ceiling of a room, showing the Wire-cloth lathing attached thereto by means of furringstrips and fastening devices embodying the present invention. 2 is an enlarged horizontal section taken through the wall of the room. Fig. 3 is an enlarged section, taken on the line .20 .r of Fig. 1, illustrating the manner of securing the furring-strips to the beams overhead and the cloth to the strips. Fig. 4 is a view similar to Fig. 3, illustrating a modification in the manner of securing the cloth to the furring-strips. 5 is a section taken on the line .1 of Fig. 4; and Figs. (3 to 13 illustrate various other modifications, all of which will be hereinafter explained.

Referring particularly to Figs. 1 to 3, it is to be understood that A represents an ordinary brick wallt'or example, the wall of a room; B, the ordinary iron beams employed to support the ceiling of the room and the floor of the room above; ordinary wirecloth-lathing material; and D, the i'urringstrips which are used as a means of securing the lathing to the wall and to the beams B. The furring-strips D are composed of sheet metal bent or corrugated, so as to assume substantially the shape of the letter W in crossseotion. The strips D, made in suitable lengths to be conveniently handled, are placed along the wall at suitable distances from each other and temporarily secured in position in any suitable manner. The wire-cloth C is then placed upon the furring-strips, it being preferably doubled under the strips at the corners, as shown at the left of Fig. 2. When the furring-strips andthe wire-cloth are in position, tightening-strips a, formed of two or more wires twisted together, as shown, so as to provide loops 1) at proper intervals, are placed along the wire-cloth over the furringstrips, and suitable nails or screws, 0, are passed through the loops 1) of the tighteningstrips a, and through correspondingopenings in the furring-strips, and driven into the wall. As the nails or screws 0 are driven into the wall their heads will come into contact with the strips a and force them and the wirethe furring-strips and the wire-cloth to the beams 13 to form the ceiling the furrin strips are first secured to the beams by means of clips cl,which overlap the flanges of the beams,

and are secured to the furring-strips by means of bolts e, as best shown in Figs. 1 and 3. The cloth is then placed under the furringstrips, with the tightening-strips a upon its under side, and the strips and the cloth are the lsecr red to the furring-strips by means of spring c 'ps' or hooks f, which are passed over-tlg ti ghtening-strips and through the meshes of the cloth and have their ends sprung into openings in the sides of the fur- .ring-strips, as shown in Fig. Theclips f are made of SPllllg-\Vl].6, so that they can be readily sprung into position without the use of special tools or implements for thepurpose, and are of such form that when in position they force the tightening-strips a, and the wire-cloth into the corrugations of the furring-strips, so as to take the slack out of the cloth the same as when the tighteningstrips are held in position by means of the nails or screws.

The construction which has thus been described embodies the invention in its best form; but various modifications may be made without whollydepartin g from the invention. The clips f, instead of being of the form shown in Fig. 3, may be of the form shown in Fig. 6 that is to say, they may be elongated so as to hook over the tops of the furring-strips, i11- stead of passing through openings in the sides of the stripsor the f urrin -strips, instead of being provided with openings in their sides to receive the ends of the clips, may have their edges turned inward or outward, as shown in Figs. 7 and 8, so as to provide locking-flanges which will engage with the ends of the clips when the latter are sprung into position, and when the furring-strips are made of this form the clips f will be of the form shown in Figs. 7 and 8. In either of these cases, however, the clips will perform the same function as that already described.

In some cases it may not be necessar r to tighten the wire-cloth, or it may be desirable to tighten it by other means than by the tightening-rods a, and in such case the rods can be omitted an dftlTeiclfiisijf usedjfljdneftosecure the cloth to the furring-strips, a s sliown in Figs. at and 5. The ti ghtenin g-strips a. may be made continuous; or they may be made in short or comparatively short pieces; or instead of being made of twisted wire, as shown in Figs. 1 and 2, they maybe formed of flat rods, as shown in Fig. 3, the rods being, if necessary, provided with suitable openings or slots to receive the nails or screws.

It may not always be desirable to employ the clips (Z and bolts 6 to secure the furringstrips 1) to the beams B, and in such case the fun'ingstrips can be fastened to the beams by screws 0, as shown in Fig. 9; and when screws are thus employed they may also be passed through the tightening-strips a, and thus serve not only to secure the furring-strips to the beams, but also to secure the cloth to the furrin -strips and at the same time effect the tightening of the cloth, as shown in Fig. 10.

The furring-strips will preferably be corrugated, so as to assume substantially the form of the letter W in cross-section, as by this means the strips are made comparatively light and yet are very strong and rigid, so as to sustain a great weight or resist great press ure; and in using the strips the upper or open end of the W will preferably be placed against the wall or the beams. The strips may, however, be reversed, as shown in Figs. 7, 8, and 13; and in some cases strips of sufficient strength may be produced by corrugating the metal, so that it will assume the shape of the letter U in cross section, as shown in Figs. 1.1 and 12. In all cases, however, the furring-strips are so corrugated as to provide a plurality of bearing-edges for the cloth.

In some cases, also, it may not be desirable or necessary to employ the clips f for securing the wire-cloth to the furring-strips, and in such case the cloth may be secured to the strips by providing the strips with prongs g,

into which single strands of the wire of the cloth can be forced when the cloth is placed in position. By then bending the prongs upward or inward the cloth will be firmly secured to the furring-strips, as shownin Figs. 1.1, 12, and 13.

It will not in all cases be necessary to employ two of the clips (Z and bolts 6 at each one of the beams B. In some cases one of the clips at each beam, as shown in Fig. 12, will be all that will be necessary.

hat I claim is i 1. A furring-strip for use with wire-cloth lathing, consisting of a strip of sheet-metal. corrugated longitudinally, so as to present a plurality of bearing-edges for the lathing, substantially as described.

2. The combination, with the flanged beams B, of a furrin -strip, D, made of sheet metal and corrugated longitudinally, so as to provide a plurality of bearingedges for the lathing, the clips cl, engaging with the flanges of the beams and with the furring-strip, and the bolts e, for securing the clips to the strip, substantially as described.

3. The combination, with the furring-strip D, having a plurality of bearing-edges for the wire-cloth, of the Wire-cloth (J, and the clips f, formed to engage with the furring-strip to IO for forcing said tightening-strips between the bearing-edges of the fuming-strips, whereby the Wire-cloth lathing is tightened, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
